There is. Display properties, Advance button, general tab.
Defaulted to 72 DPI in win 9x and 2000.
Defaults to 96 in Windows XP and probably Vista. Can be set to a 
"standard" 120 DPI or an arbitrary custom value.
The main problem, is that many applications' display will break down if 
you increase the DPI setting past 96. Some web page layout will also get 
broken if you change your DPI setting. That's why using absolute PIXEL 
values is realy bad.

A viable solution is to sellect the apearance tab and increase the point 
size of your characters. That won't affect the graphics elements but 
will make your text large enough to be read.
Selecting a good high readability font also help.
